Yep — it does.
This manual includes full factory diagnostic coverage for all Diagnostic Trouble Codes (DTCs), just like what GM techs would use at the dealership. That means you’ll get:
- Complete lists of manufacturer and OBD-II codes across all systems — engine, transmission, ABS, airbag, HVAC, infotainment, etc.
- Detailed troubleshooting workflows for each code with the exact steps to isolate the fault, test components, and rule things out.
- Verified electrical specs, reference values, and sensor thresholds so you’re not just guessing.
Whether it’s a random check engine light or some annoying intermittent issue, this will walk you through it all — no fluff, no guesswork.
Hope that helps!
